We also very fond of using short notations and different Area specific phrases to interpret our meanings and visuals.
When it comes to computers, who are totally relay on Mathematical computation, This task suddenly became very problematic to make computer understand what human want to tell them or which sentence should be interpreted into which meaning? Thus opens a vast variety and opportunity for researchers into this field.
Although there are lot of works already done in this field but this field is not gonna end as there are lot of human languages out there in world that it is defiantly requires lot of skilled man power from that specific language domain to translate all developed methods for other languages. Lot of work which is already done in this field is only specific to mostly English. Although companies like Google and Microsoft invest lot of money into other languages as well. Yet the number of languages are limited.
So if you want to do research on this field there is lot of potential in it. You can pick your own Native language and could apply pre-built techniques to that language. NLP Famous Algorithms
